A week removed from their blockbuster signing of defensive end Mario Williams, the Bills continued their defensive line overhaul, reportedly agreeing to a four year contract with defensive end Mark Anderson (Patriots).

There’s no word yet on the exact financials for the deal, but it should be reasonable given Anderson’s average level of production.

Anderson, 28, spent the first five seasons of his career with the Bears, followed by a season in Houston and then last year in New England. Throughout his career, Anderson has totaled 163 tackles and 35.5 sacks.
